IMPROVE M ENT l N JOURNAL-BOXES.

Specification forming part of Letters Patent No. 201,197, dated March12, 1878; application filed November 6,1877.

To all whom it may concern:

Be it known that I, CHARLES T. PORTER, of Newark, in the county of Essexand State of New Jersey, have invented a new and Improved Journal-Box,'of which the following is a specification:

Figure l is a plan View of my improved journal-box, having the coverremoved. Fig.2 is a sectional elevation taken on line as m in Fig. 1.Fig. 3 is a detail perspective view of the gib and Wedge.

Similar letters of reference indicate corresponding parts.

The invention will first be described in connection with the drawing,and then pointed out in the claim.

In the drawing, A is a pillow-block, of the usual external form, andprovided with the cap B, for confining the journal-box O.

The journal-box O, which is cylindrical in form, is composed of an upperpiece, a, lower piece I), and adjustable side pieces or checks 0. All ofthe pieces a b c of the box are provided with a central rib, d, which isfitted to a corresponding groove in the pillow-block, and prevents endmotion in the box. The box is prevented from turning by lug-pins d,fitted to holes in the pillow-block.

Recesses e are formed at the ends of the pillow-block for receiving keysor wedges f, by which the side pieces 0 are adjusted. The inclined faceof each wedge is placed in contact with an inclined bearing-surface, 9,formed on the outer side on each of the pieces 0 at p their ends. Afterthe wedges are placed the gibs or thickening-pieces h are placed betweenthem and the raised portion 1' of the inner wall of the pillow-block.These gibs are tapered for a short distance at their lower ends, torender them easily inserted; and they are provided with heads at theirupper ends, which engage the upper ends of the wedges as they are drawnupward.

Screws 70 pass through the cap B into the ends of the wedges, for movingthem, and by this means adjusting the side pieces 0. The screws k areprevented from turning by setscrews It, that are inserted in the bosseson the cap B, through which the screws 70 pass.

By my improved construction I am enabled to place the supporting-wedgesas near as possible to the line of thrust of the engine-that is, at theextreme end of the box against which the boss of the crank-diskrevolves.

The horizontal engine is, by my improvement, made equal to the verticalengine in supporting the shaft in the direction of the line of centers.

Having thus fully described my improvement, I claim as new and desire tosecure by Letters Patent- The combination, with pillow-block A and capB, of the journal-box having externallyinclined checks 0, the wedges f,and the gibs h, arranged as shown and described.
